Title: Electric control system
IPC: H05B7/11
Filed: 1956-03-21
Abstract: 827,292. Control systems for resistance welding. SQUARE D CO. March 21, 1956 [April 25, 1955], No. 8775/56. Class 38 (4). A circuit for controlling the passage of alternating current to a load, which circuit comprises a number of electron discharge means and having further means for rendering the discharge means operative for successive half-cycles such that during the first half-cycle in an operational sequence the electron discharge means are rendered conductive later than in the succeeding half-cycles of the sequence. In a welding control system where a welding transformer 55 is supplied by a pair of oppositely-connected ignitrons 53, 54 an operational sequence is initiated by closure of a switch 86 which allows a valve 81 to conduct, thereby energizing from a transformer 85 a relay 87 which is selfmaintained over a contact 89 thereon. Operation of relay 87 also operates contacts 4, 19, 28, 34. Closure of contact 4 energizes a solenoid 3 whereupon the welding electrodes act to apply pressure to the work to start the " squeeze " period. A capacitor 18 and resistors 16, 17 determine the length of the " squeeze " period. At the end of this period a valve 22 is rendered conducting and this causes a further valve 38 to become conductive, a capacitor 42 being used to ensure that valve 38 becomes conductive at the beginning of a positive half-cycle of the anode voltage. Conduction of valve 38 energizes relay 47 to close contacts 30, 40 and, after an inherent delay, contact 20. Closure of contacts 30, 40 allow the ignitrons 53, 54 to conduct under control of thyratrons 97, 105, thereby passing current to the welding transformer 55 for a time determined by a resistor 32 and a capacitor 33. When the contacts 30, 40 close the ignitrons fire with a lag governed by a bridge circuit including windings 111, 112 of a transformer 113, a capacitor 114 and resistors 115, 116, a transformer 101 being connected to the intermediate points. Resistor 115 is adjusted to give an optimum lag of 85 degrees so that for the first half-cycle of welding current before contact 20 closes the ignitron 53 fires with a lag of 85 degrees, giving a low magnetizing current transient. In the next half-cycle contact 20 closes, shorting out part of the resistor 115 so that the ignitrons now fire with a lag less than 85 degrees for each of the succeeding half-cycles in the sequence. At the end of the " weld " time, valves 58, 67, 73 co-operate to determine the " hold " time at the end of which valve 81 cuts off to end the weld sequence. In another embodiment contacts 30, 40 are replaced by a single contact in which case rectifiers are required in the igniter circuits of the ignitrons.

Abstract: 526,564. Forming articles from glass tubing. KIMBLE GLASS CO. March 20, 1939, No. 8864. Convention date, March 29, 1938. [Class 56] A machine for forming a lip on one or both ends of a tubular glass blank comprises means for heating one or both ends of the blank until the glass is plastic, means for rotating the blank rapidly to form the plastic glass into a lip by centrifugal force, and a gauging device for limiting the diameter of the lip. The blanks 31, Fig. 1, are fed from a hopper 32 and come to rest on pairs of overlapping discs 22 by which they are rotated. The blanks are moved through the machine by pairs of standards 34, Fig. 1, that project upwards from a bar 37. The upper end of each standard has a projecting part 34<SP>1</SP> which is inclined downwards in the direction of movement of the blanks. The bar 37 is reciprocated vertically by rotating cams 44, and when it is lowered the blanks rest on the rollers 22. When the bar is raised, the blanks are lifted by the standards 34 and roll down the inclines 34<SP>1</SP> and are then transferred to the next pair of discs 22. The cams are so shaped that a number of blanks are fed into the machine and then are allowed to rest on the discs while one end of each is heated and flared. The blanks are then moved forwards and the other ends are flared. Skewed discs 70 press on the blanks, while they rest on the discs 22, and bring them into contact with stop rails 65, Fig. 2. The glass is heated by burners 51 mounted on a sliding carriage 52 which is reciprocated horizontally to bring the flames below the ends of the blanks and to remove the flames when the glass has softened. This latter movement brings gauge tools 62 to a position where they make contact with the lips which are formed by the plastic glass and limit their diameter. In a modification, the blanks are carried by a pair of notched discs which move continuously. A second pair of discs, rotating at a greater speed, engage and spin the blanks. The blanks are carried past one or a number of burners, and the spread of the plastic glass is limited by bifurcated gauging devices. In another modification, the blanks are carried by an endless conveyer belt.

Abstract: 107,389. Bradley, L. June 21, 1916, [Convention date]. Gases, electrically precipitating suspended particles from.-In electrical apparatus for separating suspended matter from gases, uniformity of flow of the gases in the tubes of the apparatus is secured by interposing in the apparatus constrictions in the path of the gases at the inlet or outlet of the tubes but not of both. The general arrangement of apparatus described comprises a fan 22 which draws the gas to be purified from flues 2, 4 and injects them into a chamber 5, with which the flue 4 also communicates by a damper 21. Steam or water or other vapour such as sulphuric acid may be injected from a pipe 23. From the chamber 5 the gas to be purified passes through pipes 6 having valves 7 to the dust-separators 8 in which it flows downwardly and thence passes by pipes 9 having valves 10 to a chamber 11, thence by pipes 12 to other dust separators 14 in which it flows upwardly, and thence by pipes 15, and flues 17, 19 to a stack 20. The dust-separators consist of a number of tubular separating electrodes 24 connected to earth and wire electrodes 31 supplied with high-tension current from a connexion 45. The tubes 24 may be of square section- and arranged in groups with spaces 25 between them as shewn in section in Fig. 3. Hammers 40 are arranged to strike the outsides of the tubes 24 to detach the dust which falls into hoppers 43 and is removed through valved chambers 44<1> which communicate by pipes 136 with the hoppers 43 to avoid the blowing back of the dust when the chambers are opened. A partition 26 extends horizontally across the spaces 25, the gas passing from the chamber 5 into the upper part of the spaces 25 and thence through constricted openings 29 into the tubes 24 whence it passes to the lower space 25<1> and out to the chamber 11. Sliding doors 30 control the size of the openings 29. The electrodes 31 are hung from insulators 32 and weighted at 38. They are spaced by a bottom conducting frame 37 anchored at the corners at 39. Many modifications are described, the variations being mainly in the form and position of the constricting device 29. The constricting device may con. sist of a screen of wire or cotton cloth or other foraminous material arranged over the top of the tubes 24, or the tops of the pipes 24 may be contracted. The four outer corner tubes of a group mav be arranged in outwardly inclined directions so that their wire electrodes may be used to position the lower electrode frame 37. It is preferred to keep the apparatus under pressure to avoid the inward leakage of cold air. Specifications 119,236, 119,237, 119,238, 120,573, and 17840/12 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the subject-matter of Specifications 119,236, 119,237, 119,238, and 120,573 This subject-matter does not appear in the Specification as accepted.
